I had this done on a 20 ft freestanding brick wall.
They had 4 dudes dig three holes along the length of the side it was leaning toward, they dug beneath it a bit and started lifting it with bottle jacks. Once they got it where it needed to be they supported it with concrete cylinders, and excavated a large cavity to fill with concrete. They charged me 4k and were done in a day, so great deal for them, but I wasn't about to DIY that.
So the issue I think I see with your plan to push with a back hoe is you can't really apply force to the top of the column because the brick work will not work in tension, so you'd be in the state of having to lift it from beneath with the back hoe.
It could work but I feel like jacks would be more appropriate. Less error prone, you could easily fuck things up with a mistake on the back hoe.
Having seen it done on a 20 ft wall, I'd feel sorta comfortable doing it on a column. Seems less risky.

I bet if you braced the column with a bunch of 4x4's, you could push on it with the excavator to straighten it up. The 4x4's would help spread the the load over the height of the column.
Then again, you might just collapse the whole thing, since I'd bet that things hollow. But then OP could do a follow up question about DIY brick laying.

I’d do this if i were to give it a go.
